PENILE INJECTION THERAPY - ICP

Penile injection therapy or ICP has been in use for about 30 years. The injections consist of various combinations of Prostaglandin, Papaverine and Phentolamine. These drugs were initially discovered to be an effective treatment when one of them was accidentally injected into a patient's penis during heart surgery. The patient developed a solid erection for over an hour and this field of medicine was born.

The medicine, also called ICP is applied with an auto-applicator. It is extremely user friendly and just about anyone can do it. The injection is with a 30 gauge ultra-fine needle that goes about 1/2 inches into the side of the penis. The injection can be applied on either side of the penis and the medication will spread throughout the entire penis. Because the spring loaded applicator inserts the needle quickly, most men find that the injection itself is relatively painless. They feel the needle, but most men say that it is not bothersome. Many patients do not feel the injection at all and others relate that it feels like a mosquito bite.

The amount and strength of the medicine that needs to be injected varies from person to person. We will determine the smallest amount of medicine that is necessary to achieve an adequate erection.

The goal of penile injection therapy is to achieve a strong erection that is suitable for sexual intercourse and lasts about 30 - 45 minutes. The medicine starts to work about 5 - 15 minutes after the injection is given. It may be used once a day and as often as 3 times each week.

The erections that a patient gets from penile injection therapy are the same as his natural erections, as both are caused by the penis being filled with blood.

Patients choosing to use penile injection therapy are tested in the office to determine the optimal dose for them to use at home. Patients are instructed in great detail on exactly how to use and apply penile injection therapy, how often they may use it and how to vary the site of the injection.

Penile injection therapy or ICP, when used properly, is a relatively safe and effective treatment to preserve a man's sexual function. Because the needle is penetrating the skin on the side of the penis, possible side effects include bruising or the formation of a small hematoma at the injection site. Occasionally a small nodule or lump of fibrotic scar tissue may form at the injection site, particularly if the same injection site is always used. Patients who follow our instructions and who do not use the medicine more than 3 times each week and who always vary the injection site and apply pressure for at least 2 minutes after the injection is given usually do not have any of these problems.

While
men with diabetes and/or who are obese may usually use penile injection
therapy with relative safety, they tend to have a higher incidence of
developing scar tissue in the penis.

While these medications are relatively safe for men to use, all medications have certain side effects. This medication may cause a prolonged erection. While our goal is an erection that lasts for 30 - 45 minutes an erection lasting 1-2 hours will cause no harm. However, an erection lasting more than 4 hours requires immediate medical attention. While the medication is relatively painless for many patients, the medications may cause some achiness or dull pain in the penis. This discomfort usually dissipates after using the medicine a few times; the patient's formula can often be changed to eliminate the pain if necessary. Rarely a patient may feel dizzy from the medicine. Even rarer are heart rhythm abnormalities and effects on liver enzymes.

Only Prostaglandin is specifically FDA approved for erectile dysfunction and comes in the brand names of Caverject® and Edex®. Prostaglandin is the shortest acting of the various vasodilators used to induce an erection, but is also the most likely to cause discomfort and less likely to induce an erection than when used in combination with the other vasodilators. For these reasons, most clinicians treating erectile dysfunction or trying to preserve a man's sexual function use combinations of the various vasodilators. While the individual vasodilators are all FDA approved for something, only Prostaglandin is FDA approved for erectile dysfunction. So when these vasodilators are used in combination, this compounded or combined injectable medication is called an off-label, but legal use of individually FDA approved drugs. While Caverject® and Edex® are available in regular pharmacies, the compounded medications are available only through a compounding pharmacy. All of the compounding pharmacies that we use are accredited by PCAB - the Pharmacy Compounding Accreditation Board.

Most men can safely use penile injection therapy. Men who are taking aspirin or other blood thinners may bruise more easily, but may still use the medication. Moderate alcohol consumption or eating prior to usage will have little effect on the medication.

Men who have poor manual dexterity or who are legally blind may need to have their partner apply the ICP. Men who have sickle cell disease, a penile implant or who have abnormal liver enzymes may not use this medication. Men who have dizziness from penile injection therapy, which probably results from a condition called venous leakage, should not use this medication.
